The patents, which are said to cover technologies like software and networking, would significantly increase the size of Facebook’s intellectual property portfolio. As of December, the company had 56 issued patents and had filed 503 U.S. patent applications, while rival company Yahoo! had more than 3,300 patents and applications.

Yahoo! is accusing Facebook of infringing patents covering Internet privacy, advertising, and information sharing. Yahoo asked for an order barring Facebook from infringing 10 patents and is seeking triple damages.
